I'm shocked at the low ratings this drama had. It is such a beautiful and unique story and one that will stay with me for a long time. Who knew maths could be so beautiful. This drama gives the viewer the opportunity to see the world through the lens of a mathematician. True slow burn love which is never made to feel inappropriate and the fight for justice against the corruption of an elitist education system. It was never too dark or depressing. I found this story with the backdrop of maths to be very deep and poignant without being boring. The ML and FL and the headteacher were excellent in their roles. I can't believe how young the FL leads looks ....she looked the same age as the ML. This drama deserves to be a hit and tbh I've seen so many K dramas C Dramas Lakorns and J dramas and this is really one of the most unique of them all. This is a must watch imo.
